It offers you a flexible solution to cover all your structural engineering needs from the foundation up. STAAD is a comprehensive structural finite element analysis and design application that allows users to perform analysis on any structure exposed to static, dynamic, wind, earthquake, thermal, and moving loads. STAAD comes in different variations so you can choose what’s best for you. STAAD is a popular structural analysis application known for analysis, diverse applications of use, interoperability, and time-saving capabilities. STAAD helps structural engineers perform 3D structural analysis and design for both steel and concrete structures. A physical model created in the structural design software can be transformed into an analytical model for structural analysis. Many design code standards are incorporated into STAAD.Starting Price: $3,000 per year -

gTTS
gTTS
gTTS (Google Text-to-Speech), a Python library and CLI tool to interface with Google Translate's text-to-speech API. Write spoken mp3 data to a file, a file-like object (bytestring) for further audio manipulation, or stdout. Or simply pre-generate Google Translate TTS request URLs to feed to an external program. Customizable speech-specific sentence tokenizer that allows for unlimited lengths of text to be read, all while keeping proper intonation, abbreviations, decimals and more. Customizable text pre-processors which can, for example, provide pronunciation corrections.Starting Price: Free -

fe-safe
Dassault Systèmes
Material usage optimization has become the cornerstone of the transformation that the industry is currently experiencing. Manufacturers relentlessly pursue lightweight and robust components to deliver cost-efficient production with lower warranties, minimal recall costs, and accelerated timelines. Advanced finite element analysis is a staple in design stress calculations. Many companies still rely on manual stress point selection for spreadsheet analysis to conduct fatigue analysis. This approach is time-consuming and unreliable because it increases the risk of overlooking critical failure locations. fe-safe is the technical leader in fatigue analysis software for finite element models. fe-safe has set the benchmark for fatigue analysis software since the early 1990s in close collaboration with the industry. The fe-safe software suite is a world-leading technology for durability analysis from FEA. It directly interfaces with all major FEA suites. -

DIGIMU
TRANSVALOR
DIGIMU® generates digital polycrystalline microstructures representative of the material's heterogeneities (compliance with the topological characteristics of the microstructure). The boundary conditions applied to the REV are representative of that experienced by a material point at the macroscopic scale (thermomechanical cycle of the considered point). Based on a Finite Elements formulation, the various physical phenomena involved during metal forming processes are simulated (recrystallization, grain growth, Zener pinning due to second phase particles, etc.). In order to improve digital precision and to reduce computation times, the software is capable of providing a precise description of the interfaces (grain boundaries) while using an appropriate number of elements thanks to a fully automated anisotropic meshing and remeshing adaptation technology. -

NCSIMUL 4CAM
Hexagon AB
All-in-one NC programming. NCSIMUL 4CAM is the NCSIMUL SOLUTIONS module that complements existing CAMs to simplify NC programming and increase the flexibility of CNC machines. It allows you to change machines on the fly without new CAM programming. From the main CAMs (CATIA, NX, CREO, TOPSOLIDCAM, MASTERCAM, etc.) or existing NC programs (ISO format), NCSIMUL 4CAM directly generates, without external post-processor, native NC programs, verified and optimized taking into account the physical means of the workshop (tools, cutting conditions, kinematics, machine controllers, etc.) Automatic extraction of trajectories from APT / ISO files and generation of the NC program. One-click machine change and on-the-fly generation of a new NC program without errors. Use of existing NC programs to optimize the machining process by simple copy / paste. Elimination of external post-processor thanks to integrated NC processor. Feedback of changes in the machining process. -

JSFiddle
JSFiddle
JSFiddle has the notion of panels (or tabs if you switch into the tabbed layout), there are 4 panels, 3 where you can enter code, and 1 to see the result: HTML - structure code, no need to add body doctype head, that's added automatically, CSS - styles. You can switch pre-pocessor to SCSS, JavaScript - behavior. There are many frameworks and code pre-processors you can use. Once you enter code, just hit "Run" in the top actions bar, and the fourth panel with results will appear. SFiddle allows you to switch the layout of the editor from the classic 2x2 grid to something that suits your needs. In addition to the grids mode it also has a tabbed mode. Grids are fully resizable. As an addition resizing the Results panel will tell you its width (handy for working on media queries).
